ATTORNEY my invention;

Patented Aug. 1, 1933 1 UNITED STATES PATENT OFFICE 7 CORNER FASTENER John M. Richens, Jacksonville, Fla. Application November 4, 1931. Serial No. 573,031

3 Claims. (01. 2092.)

My invention relates to improvements in corner fasteners and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of the invention is to providea device consisting of a single member which may be inserted at the corner joint of a frame or other similar device and which when driven into the frame will fasten the corners securely.

A further object of the invention is to provide a corner holding or fastening means which can be made inexpensively and which requires but little work to apply it to the corner.

A further object is to provide a fastening device in which only a saw and a hammer are necessary to apply the device.

Other objects and advantages will appear in the following specification and novel features of the invention will be pointed out in the appended claims.

My invention is illustrated in the accompanying drawing forming a part of this application, in which:

Figure 1 is a perspective view showing my improved fastening device applied to a corner;

Figure 2 is a plan view of one embodiment of Figure 3 is an edge view looking toward the apex of the triangular member;

Figure 4 is a sectional view through a portion of the part showing the positions of the ears before being driven home;

Figure 5 is a similar section showing the position of the ears after they are driven in; and

Figure 6 is a view similar to Figure 3 showing a modified form of the device.

In carrying out my invention I provide a triangular metal plate 1 which may be made of any suitable material. The plate is a right angle triangle and along the sides adjacent to the right angle are stamped ears 2. It will be observed that alternate ears are bent upwardly from the plane of the body portion, the remainder of the ears being bent downwardly or toward the opposite face of the body portion as shown in Fig. 3. This forms a staggered arrangement. The ears are further bent substantially at right angles to the body portion and are provided with notches 3 so as to form a pair of teeth or points 4 for each ear.

As it will be seen from Fig. 4 the body portion of each ear 2 is bent substantially at 45..

From the foregoing description of the various parts of the device the operation thereof will be readily understood. 5 and 6 represent'the members of the frame or similar object which is to be joined together. These members are cut with a miter along a i5 line '7 and a slot 8 is cut through these members, the plane of the slot being parallel with the frame of the members.

The body portion 10f the connecting device is placed in theslot as shown in Figure 1 and the ears 2 are pounded down and bite into the wood thus holding the corner securely.

In Figure 6 I have shown a modified form in which the ears 2:11 on one edge of the body portion adjacent to the right angle are first bent at right angles to the plane of the body portion, the ears being staggered as in Figure 3, the ends of the ears being bent at right angles again as shown at 2y. The cars 2 on the other edge adjacent to the right angle are arranged as shown at Figure 3.

In this form of the device the body portion is placed in the slot 8 and the ears 2x are driven straight into the wood. Then the ears 2 are driven in firmly securing the fastening member.

I claim:

1. A corner fastening member comprising a body portion consisting of a right triangle, said body portion having ears struck up on the edges adjacent the right angle, the bases of certain of said ears being bent at substantially 45 from the plane of the body portion, certain of said ears being bent' toward one face and the other ears being bent toward the other base and all of the said ears having inwardly bent ends, provided with teeth.

2. The combination with corner members disposed at right angles to each other and having abutting bevelled ends, said corner members being provided with a slot extending inwardly from the apex of the corner and parallel to the faces of said corner members, of a fastening member comprising a body portion consisting of a right triangle, said body portion having ears struck up on the edges adjacent the right angle, certain of said ears being bent toward one face of the corner members and other ears being bent toward the opposite face of the corner members, all of said ears being further bent to enter the corner members in a plane substantially parallel with the'faces of said members, and being pro vided with teeth at their ends.

3. A corner fastening member comprising a body portion consisting of an isosceles triangle, said body portion having ears struck up on the edges of the equal sides, the bases of certain of said ears being bent at substantially 45 from the plane of the body portion, certain of said ears being bent toward one face and the other ears being bent toward the other face and all of said ears having inwardly bent ends provided with teeth.

JOHN M. RICHENS.
